How much money would need to be deposited into an account earning 5.25% interest compounded annually in order for the accumulate
scoundrel [369]
Answer provided by our tutors

P = the principal


t = 25 years the time in years


r = 0.0525 or 5.25% annual rate


m = 1 compounding periods per year


i = 0.0525 or 5.25% interest rate per period


n = t*m = 25 total number of compounding periods


A = $75,000 future value


A = P(1 + i)^n


P(1 + i)^n = A


P(1 + 0.0525)^25 = 75000


by solving we find:


P = $20,869.34

Write the equation of the line with a slope of 2 that contains the point (3, 9) .
mr Goodwill [35]

Answer:

Step-by-step explanation:Here the slope of the line = m = 2

The line passes through the point ( x 1 ,  y 1 ) = (   ,  9 ).

The equation of the line with slope  m  and passing through the  point ( x 1 ,  y 1 ) is given by ( y -  y 1 ) = m ( x  -  x 1 )

( y  -  9 ) =  2  (  x  -  3 )y  -  9  =  2 x -  6

Collecting terms in one side

0  =  2 x  -  y  -  6  +  9

2 x  -  y  +  3  =  0

Hope this helps x
